TECHNICAL FIELD

The present disclosure relates to a door handle arrangement, andespecially an arrangement for a door handle used in industrialapplications.

BACKGROUND

In the field of handles for doors, cabinets, and windows, the use of adoor handle as a means to move a latch or locking device for opening orclosing of doors is a common way of arranging the opening or closing ofa door. In some industrial applications such as electrical enclosures orventilation ducts, there may be a need to control the opening of thedoor such that it is not uncontrollably flung open. This may for examplebe the case when the door is located in a ceiling or that there may be apressurized fluid in the space to be opened.

The pressurized fluid may cause an explosive opening of the door when alock or handle is opened. This may injure a user opening the door.Hence, there is a need for a door handle solution which prevent theopening of a door to a pressurized space to injure a user.

SUMMARY

It is an object of the present invention to provide an improved solutionthat alleviates the mentioned drawbacks with present devices.

The invention is defined by the appended independent claims, withembodiments being set forth in the dependent claims, in the followingdescription and in the attached drawings.

According to a first aspect of the invention, there is provided a handlearrangement for a door comprising a handle arranged to move rotationallyaround a rotational axis C between an open state and a closed state, anda locking means for engaging with a locking element on a door frame, andfurther comprising an intermediate link arranged between the handle andthe locking means and arranged for transforming the rotational movementof the handle to substantially linear movement of the locking means, aconnection element, wherein the handle is connected to the intermediatelink by the connection element, and the intermediate link is arranged toperform a movement following an arcuate path when the handle is movedbetween the open state and the closed state.

In another solution, there is provided a handle arrangement comprising ahandle and a locking clamp for engaging a locking element on a doorframe. The locking clamp is arranged to rotate around a first axis froma locking position to an intermediate position when the handle is movedfrom a closed state towards an intermediate state. The locking clamp isarranged to move linearly along a second axis from the intermediateposition to an open position when the handle is moved from theintermediate state towards an open state. The handle arrangementcomprises a resilient means arranged to, by a resilient force, keep thelocking clamp from moving from the intermediate position towards theopen position until a force applied in the direction of the linearmovement of the locking clamp towards the open position exceeds theresilient force of the resilient means.

With this arrangement, a handle arrangement which may be opened inseveral steps is provided. By this multistep opening, the opening of adoor, cabinet or window may be performed in a controlled manner. Thearrangement further provides a simple construction where no additionalparts are required to achieve the multi-step function of the handlearrangement.

The intermediate position of the locking clamp and intermediate state ofthe handle are defined as a position or state in-between the open andlocking/closed position or state respectively.

When the locking clamp is rotated around the first axis from the lockingposition into the intermediate position, the locking clamp may be partlyreleased from a locking element of a door frame or wall such that thedoor remains closed but the pressure may be released. This intermediateposition, allowing the pressure to drop, ensures that the door is notuncontrollably flung open due to a pressure difference between theenclosure to be opened and the surrounding area. It may also serve as aprotection for a door which opens downwards from for example a ceilingor tilting wall such that the door does not fall downwardsuncontrollably.

When the pressure has been released, or control achieved, the handle maybe turned from its intermediate state to its open state, which alsocauses the locking clamp to move from its intermediate position into itsopen position. In the open position, the locking clamp is fullyretracted and released from the locking element such that the door maybe opened in a controlled manner.

According to one embodiment, the handle arrangement may further comprisean actuator, wherein the actuator may be arranged between the handle andthe locking clamp and arranged to move linearly along the second axis.The actuator may serve as a means to push or pull the locking clamp intothe open, intermediate, and locking positions by executing a force onthe locking clamp. When the handle is moved from the closed statetowards the intermediate state, the actuator may pull the locking clampsuch that the locking clamp rotates to the intermediate position. Duringsuch rotation, the resilient means may prevent the locking clamp frommoving linearly towards the open position. When the handle is movedfurther towards the open state, the actuator may pull the locking clampfurther to move linearly along the second axis towards the openposition.

According to a further embodiment, the actuator may be coupled to thelocking clamp by a link. By coupling the actuator to the locking clampby a link, the locking clamp and the actuator may move along the secondaxis between the open and intermediate positions of the locking clampand the locking clamp may rotate around the first axis between theintermediate and locking positions while the actuator remains to movealong the second axis.

In another embodiment, the link may be rotatably arranged to the lockingclamp at a first end and rotatably arranged to the actuator at a secondend. The rotatable connection between the link and the actuator and thelocking clamp respectively, may provide for a movement where the secondend arranged to the actuator may move along the second axis and rotatein relation to the actuator, while the first end may rotate in relationto the locking clamp and rotate around its second end away from thesecond axis.

According to another embodiment, the link may enable the rotation of thelocking clamp from the locking position to the intermediate positionwhen the actuator moves linearly along the second axis. The link mayrotate in relation both to the locking clamp and to the actuator,respectively, such that when the locking clamp is in the lockingposition, the second end of the link and the part of the actuator towhich it is rotatably connected, may be located on the second axis whilethe first end of the link may have been rotated away from the secondaxis around its second end, being rotatably connected to the lockingclamp in its locking position. The rotatable connection to the secondend of the link implies that as the actuator moves along the secondaxis, the second end of the link may move with the actuator while thefirst end of the link rotates around the second end towards the secondaxis until it reaches a position where no further rotation isachievable. As the first end rotates towards the second axis, the end ofthe locking clamp to which it is rotatably attached, may also be forcedto move in this direction, causing a rotation of the locking clamparound the first axis from its locking position towards its intermediateposition. In one embodiment, when the locking clamp is in theintermediate position, the first end of the link may be offset of thesecond axis relative to the second end of the link. The first end of thelink being offset of the second axis may provide that the link, when thelocking clamp rotates from the intermediate position towards the lockingposition, pushes the locking clamp such that it is lifted at its endconnected to the link, and thereby performs the rotation. When thelocking clamp has been moved from the open position to the intermediateposition and further linear movement of the locking clamp is prevented,the link provides a lifting of the locking clamp.

In another embodiment, the second axis may be perpendicular to the firstaxis. The second axis may be the axis along which the linear movement ofthe actuator occurs while the rotation of the locking clamp occursaround the first axis. The locking clamp may also move linearly alongthe second axis as it moves between its intermediate and open positions.When the locking clamp is moved linearly along the second axis, theposition of the first axis being the rotational axis of the lockingclamp may move along the second axis.

In another embodiment the locking clamp may comprise at least one pinextending along the first axis. The at least one pin extending along thefirst axis may serve as the means around which the rotation of thelocking clamp occurs when it rotates between its locking andintermediate positions.

According to a further embodiment, the least one pin may be arranged tointeract with the resilient means. The at least one pin may furtherinteract with the resilient means such that the resilient force whichmay keep the locking clamp from moving from the intermediate positiontowards the open position is exerted on the pin.

In yet another embodiment, the resilient means may be a flat spring. Theresilient means being a flat spring may provide for shaping the springsuch that when the force exerted on the at least one pin is lower thanthe resilient force, the pin remains still or rotates around the firstaxis in its current position adjacent the flat spring and such that whenthe force exerted on the at least one spring exceeds the resilientforce, the at least one pin of the locking clamp moves from its currentposition to another position relative to the flat spring.

In a further embodiment, the locking clamp may comprise at least one pinextending along the first axis arranged to interact with the flatspring, and wherein the flat spring may comprise a flat portion and acurved portion, wherein the flat spring may be arranged to keep the pinat the curved portion in the locking and intermediate positions of thelocking clamp and wherein the pin may be located at the flat portionwhen the locking clamp is in the open position. The curved portion ofthe flat spring may have a curvature essentially similar to that of theat least one pin. The curved portion may further keep the at least onepin in position during rotation of the locking clamp. When the forceapplied in the direction of the linear movement of the locking clamptowards the open position exceeds the resilient force of the spring, theat least one pin moves past the curved portion onto the flat portion ofthe spring.

According to another embodiment, the flat spring may comprise a shoulderconnecting the flat portion and the curved portion. The portions of theflat spring may be connected by a shoulder which defines the divisionbetween the curved and flat sections of the flat spring.

According to another embodiment, the locking clamp and the resilientmeans may be at least partially covered by a housing. The housing mayprotect the locking clamp and the resilient means. The housing mayfurther provide support to the resilient means such that the relevantresilient force can be exerted.

According to a further embodiment, the resilient means may in one end beattached to the housing and in another opposite end moveable relative tothe housing. When a force is exerted on the locking clamp towards theopen position, the resilient force of the resilient means may beexceeded such that the resilient means is moved relative the housing bythe locking clamp. The resilient means may be moved such that at leastthe end being moveable relative to the housing is moved.

According to one embodiment, the resilient means may be a flat springcomprising a flat portion and a curved portion, and wherein the flatspring is moveable relative to the housing adjacent to the curvedportion.

According to one embodiment, the locking clamp may in the lockingposition be configured to prevent movement of the door relative to thedoor frame, and in the intermediate position may be configured to enablea limited movement of the door relative to the door frame but preventcomplete opening of the door relative to the door frame. In the lockingposition, the locking clamp may keep the door closed in a locked mannerand prevent opening of the door. In the intermediate position, thelocking clamp is moved to enable a partly opening of the door relativeto the door frame. The partly opening of the door may in one embodimentenable an opening of between 1-5 cm. The partly opening may be limitedby the locking clamp in the intermediate position engaging the lockingelement on the door frame. In the open position, the locking clamp maybe moved to enable complete opening of the door relative to the doorframe. The locking clamp may in the open position not engage the lockingelement on the door frame.

DETAILED DESCRIPTION

The present invention will be described more fully hereinafter withreference to the accompanying drawings. In the drawings, like numbersrefer to like elements.

FIG. 1 illustrates a door arrangement comprising a door 10 arranged on adoor frame 70. On the door 10 a handle arrangement 1 is arranged.

FIGS. 2a-2c illustrate the handle arrangement 1 according to anembodiment comprising a locking clamp 3, a handle 2, an upper 5 a and alower 5 b housing, and an actuator 4 coupled to the locking clamp 3 by alink 7. The handle 2 is rotatable around a third axis C as it is movedbetween its closed, intermediate, and open states.

In FIG. 2a the handle arrangement is illustrated with the handle 2 inthe closed state and the locking clamp 3 in the locking position. In thelocking position, the locking clamp 3 has been rotated around the firstaxis A. The extending pins 31 are located under the curved portion 81 ofthe resilient means 8 and in a first corner of the lower housing 5 b, asfurther illustrated in FIG. 6a . In the locking position, the lockingclamp 3 is configured to be pressed towards a locking element on a doorframe 70 (see FIGS. 7a-7c ), thereby locking the door 10 to which thehandle arrangement 1 is attached. Further, in the locking position, theactuator 4 is in a position along the second axis B, where it is stoppedfrom further movement along the second axis B in the direction of thelocking clamp 3 by the lower part 5 b of the housing.

The resilient means 8 may be a flat spring made of metal, hard plastics,or any other material capable of exerting a force on the extending pins31 of the locking clamp. There may be two flat springs 8 in the handlearrangement 1, one on each side of the locking clamp 3 as illustrated inFIG. 3.

The flat spring 8 is illustrated in FIG. 5 and comprises a curvedportion 81 and a flat portion 82. The curved portion 83 has a curvaturecorresponding to the curvature of the extending pin such that the pinmay rotate without any impact of the resilient force. The flat spring 8further comprises an interacting portion 84 adapted to interact with theupper part 5 a of the housing, further enhancing the resilient forceexerted on the extending pins 31. The flat spring 8 also comprises agrasping portion 85 which is adapted to grasp around the lower part ofthe housing 5 b and is fixated between the upper part 5 a and the lowerpart 5 b of the housing.

In FIG. 2b , the handle 2 is in the intermediate state. As the handle 2moves to the intermediate state, the actuator 4 moves along the secondaxis B and, via the link 7, pulls the locking clamp 3 to rotate aroundthe first axis A into the intermediate position. As illustrated in FIG.6b , in the intermediate position, the extending pin 31 is located underthe curved portion 83 and in a first corner of the lower housing 5 b.

FIG. 2c illustrates the handle 2 in its open state. As the handle 2 isrotated around the third axis C into the open state, the actuator 4moves along the second axis B and via the link pulls the locking clamp 3to move along the second axis B. When the force exerted on the lockingclamp 3 exceeds the force of the flat spring 8, the locking clamp 3 ismoved along the second axis B into the open position. As the lockingclamp 3 moves along the second axis B into its open position, the firstaxis A around which the locking clamp 3 rotates, moves with theextending pin 31 along this axis B into a second corner of the lowerhousing 5 b and to a position under the flat 82 and interacting 84portions of the flat spring 8, as further illustrated in FIG. 6c .Rotation of the locking clamp 3 around the first axis A is prevented bythe upper part 5 a of the housing in any other position than the lockingposition and the intermediate position.

FIG. 3 illustrates an x-ray top view of the handle arrangement 1 inwhich the upper housing 5 a is removed. The locking clamp 3 comprisestwo pins 31, extending along the first axis A on both sides of thelocking clamp 3. The locking clamp 3 is illustrated in the open positionwhere the extending pins 31 have been moved with the locking clamp 3along the axis B such that they are located in the second corner of thelower housing 5 b and under the flat 82 and interacting 84 portions ofthe spring 8.

FIGS. 7a-7c illustrate the movement of the link 7 as the handle 2 movesbetween the open, intermediate, and closed states. In FIG. 7a , thehandle is in the closed state and the locking clamp 3 in the lockingposition. A first end of the link 7 is rotatably connected to thelocking clamp 3 and a second end of the link 7 is rotatably connected tothe actuator 4. In the closed state of the handle 2, the second end ofthe link 7 is located with the actuator 4 on the second axis B and thefirst end of the link 7 has been rotated around the second end away fromthe second axis B.

In FIG. 7b , the handle 2 has been moved into its intermediate position.When the handle 2 is moved into the intermediate position, the actuator4 is moved along the second axis B. The movement of the actuator 4initiates a movement of second end of the link 7 along the second axisB. As the second end is pulled along the second axis B, the first endrotates around the second end towards the second axis B. The rotation ofthe first end initiates the rotation of the locking clamp 3 around thefirst axis A, from the locking position to the intermediate position.Since the link 7 is arranged between the actuator 4 and the lockingclamp 3, a force lower than the resilient force of the flat springs 8 isexerted on the locking clamp 3 when the handle 2 is moved from theclosed state to the intermediate state. Instead, the locking clamp 3rotates around first axis A.

Further movement of the handle 2 into the open state moves the actuatorfurther along the second axis B. Due to the force from the flat spring8, a force greater than the resilient force is required to further movethe locking clamp 3 from the intermediate position to the open position.When a force greater than the resilient force is applied on the actuator4, the link 7 pulls on the end of the locking clamp 3 to which it isrotatably connected and thereby pulls the locking clamp 3 into the openposition. Since no further rotation of the locking clamp 3 is possiblewhen in the intermediate position, further pulling force from theactuator 4 provides force on the locking clamp 3 to exceed the resilientforce and to move the locking clamp along second axis B to the openposition.

As an alternative, or in addition to the previously disclosed features,a handle arrangement 1 may comprise a locking means for engaging with alocking element on a door frame 70, a handle 2 arranged to moverotationally around a third axis C, between an open and a closed state,and which may comprise a connection element 21. The handle arrangement 1may further comprise an intermediate link 6 arranged between the handle2 and the locking means and for transforming the rotational movement ofthe handle 2 to a substantially linear movement of the locking means.The handle 2 may be connected to the intermediate link 6 by theconnection element 21, and the intermediate link 6 may be arranged toperform a movement following an arcuate path when the handle 2 is movedbetween the open state and the closed state.

The intermediate link 6 may be arranged to be moved between an openstate and a closed state, each corresponding to the open and closedstates of the handle respectively. In FIG. 4a , the intermediate link 6is illustrated in its closed state.

The intermediate link 6 may comprise at least one guide slot 61 arrangedto receive the connection element 21, as illustrated in FIG. 4 a.

The connection element 21 is arranged to move along the at least oneguide slot 61 when the handle 2 moves between the open and closedstates. As illustrated in FIG. 4a , in the closed state of theintermediate link 6 and the handle 2, the connection element 21 islocated at a first end of the guide slot 61. In the open state of theintermediate link 6 and the handle 2, illustrated in FIG. 4b , theconnection element 21 has been moved along the guide slot 61 to a secondend of the guide slot 61 as the handle 2 has moved from the closed stateto the open state.

The rotation of the handle 2 may result in a rotational movement of theintermediate link 6 via the connection element's 21 interaction with theguide slot 61. The handle arrangement 1 may further comprise a handlebody 9, wherein the body 9 comprises an arced portion 91. The arcedportion 91 as illustrated for example in FIG. 2a , provides a pocketbetween the handle 2 and the handle body 9, such that rotation of thehandle 2 by hand or by other gripping means, is facilitated as an areafor receiving for example fingers, for gripping the handle 2 when movingthis between its open or closed states, is provided.

The arcuate path of the intermediate link 6 may correspond to thecurvature of the arced portion 91 of the handle body 9. As illustratedin FIG. 4a , the intermediate link 6 is located on the arced portion 91of the handle body 9 in the closed state. As the handle 2 is moved toits open state, the intermediate link 6 follows its arcuate pathcorresponding to curvature of the arced portion 91 into its open stateposition as illustrated in FIG. 4 b.

The arced portion 91 of the handle body 9 may further comprise a guidetrack 92 arranged to guide the intermediate link 6 along its arcuatepath. The guide track 92, illustrated in FIG. 2c , serves as astabilizing guide when the intermediate link 6 is moved along itsarcuate path as the handle 2 is moved between the open and closedstates. The guide track 92 may be T-shaped. The intermediate link 6 maycomprise a groove correspondingly shaped as the guide track 92 andconfigured to receive the guide track 92. The intermediate link 6 may bemoveable along the guide track 92 and held in connection with the handlebody 9 by means of the guide track 92 and the groove.

The arcuate path may provide a rotation around a fourth axis D, whereinthe fourth axis D is located in the cavity of the arced portion 91 ofthe handle body 9 as illustrated in FIG. 2b . The rotation along thearcuate path may in another embodiment be around an axis located outsidethe entire handle arrangement, due to a flatter arc in the arcuate path.

The locking means may comprise an actuator 4 and a locking clamp 3. Anexample of such actuator 4 and locking clamp 3 are illustrated in FIG.4a . The connection between the handle 2 and the intermediate link 6 andthe rotational movement of these is transformed into a linear movementalong axis B of the actuator 4 and the locking clamp 3.

The intermediate link 6 may be shaped in a V-shape, wherein a firstflange of the V-shape may comprise an end rotatably connected to theactuator 4 and a second flange comprising the guide slot 61 forreceiving the connection element 21. The rotatable connection betweenthe intermediate link 6 and the actuator 4 transforms the rotationalmovement of the intermediate link 6 to a linear movement of the actuator4. The coupling between the guide slot 61 and the connection element 21translates the rotational movement of the handle 2 around the third axisC into a rotational movement of the intermediate link 6 around thefourth axis D.

A bottom portion of the V-shape may comprise an arc shaped surfaceconfigured to face the arced portion 91 of the handle body 91. The arcshaped surface has a curvature corresponding to the curvature of thearced portion 91 of the handle body 9.

The handle 2 may comprise a locking cylinder 22 and wherein the lockingcylinder 22 extends from the handle 2 along a curvature of a circle witha radius corresponding to the length of the handle 2. The connectionelement 21 may further be arranged on the locking cylinder 22. Thecurvature of the locking cylinder 22 facilitates the transformation ofthe handle's 2 rotation around the third axis C to the rotation of theintermediate link 6 around the fourth axis D.

The connection element 21 may be formed as a pin extending into theguide slot 61 on the intermediate link 6.

The movement of the handle 2 between its open and closed states,corresponds to an accelerated movement of the actuator 4, that is thedistance moved on the second axis B by the actuator when the handle 2 ismoved between the open and closed states is larger than the distance thehandle is moved.

The handle arrangement 1 according either embodiments of the disclosedinvention may further comprise a lock arranged on the locking cylinder22, which may be operated mechanically by for example a key orelectrically. The lock may serve to lock the door 10 to which the handlearrangement 1 is attached when the locking clamp 3 is in its lockingposition and the handle 2 is in its closed state such that the doorcannot be opened unauthorized without a key or to prevent unintentionalopening of the door.
